They've done it again. Already, my system was running with better power management than in Windows, but this has been increased significantly now. I had already reported about less cpu power usage during sound playback. Now the wifi and sound card's power management was during playback was improved, too.

I haven't made any exhaustive comparison tests yet, but I can now be online, surfing and listen to music with a total power consumption of around 6.8-7.5 W. As a rough comparison: With 2.6.36 the same scenario would require about 10.3-12.5 W... (each using the quite power efficient browser opera. Only the graphics driver is a different one: gma500_gfx+fbdev now v. psb+exa.)

Michael Meeks published a comparison of features. Though he is a member of LibreOffice, it appears unbiased. To make the story short: You should get LibreOffice. Development seems much healthier now than before, actually. Also, a switch to dual-licensing under LGPL 3 and MPL is under way.
